html - sendmailR 在 HTML 正文中添加额外的空间，偶尔会破坏 HTML 标签

问题描述

我为团队中的人员自动生成了个性化报告，效果很好！

唯一的问题是某些电子邮件偶尔会在 HTML 正文中间有一个额外的空间。有时，这些额外空间的位置会破坏并暴露 HTML 标记：

例如，“Consul invidunt”会读作“Consul invi dunt”。或者更糟糕的是，它会读取“< p> Consul invidunt”，并且由于额外的空间而暴露了段落标签。

唯一有效的就是制造“空间陷阱”。例如，<p> </p>在段落之后添加并希望额外的段落“落在”段落的中间，这只是一堆空格。但它并不总是有效。

由于正文中间的数据框和收件人姓名是可变的，因此此问题仅发生在某些收件人身上。那些有故障的接收者会根据我在正文中输入的内容而变化，我是否尝试用“空间陷阱”来“捕捉”空间等。

奇怪的是，如果我将 HTML 粘贴bodyhtml[['text']]到 HTML 编辑器中，HTML 看起来很完美！

我还检查了这是否是 Outlook 的问题，但发送到 gmail 时问题仍然存在。

这基本上是我的代码：

bodyhtml <- sendmailR::mime_part(paste0(
"<!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0 Strict//EN' 'http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd'>",

))

bodyhtml[["headers"]][["Content-Type"]] <- "text/html"

msg <- c(bodyhtml, sendmailR::mime_part("my_file_path.xlsx"))


sendmailR::sendmail(from = "me@email.com",
                    to = "you@email.com",
                    subject = "my subject line",
                    msg = msg)

有人有什么想法吗？请帮忙！

解决方案

我替换了前两行（DOCTYPE 和 html 标签），这似乎成功了！

"<!DOCTYPE html>",
"<html xmlns='http://www.w3.org/1999/xhtml' lang='en'>",

我发现这些链接很有帮助：
